JD.com, one of China’s largest e-commerce companies, is launching a new Beijing-based accelerator program for artificial intelligence and blockchain startups. Called AI Catapult, its first batch includes six companies: Bankorus, CanYa, Bluezelle, Nuggets, Republic Protocol and Devery.

In an announcement, JD.com said startups will work with its operational teams to “test real-world applications of their technologies at scale.” This includes its logistics unit, which recently raised $2.5 billion and claims to run the largest last-mile logistics network in China.

Though Alibaba Group is probably better known outside of China, JD.com is a formidable rival. In 2016, it recorded 658.2 billion RMB, or about $100 billion, in gross merchandise value (JD.com will announce its full-year results for 2017 next month). JD.com and Tencent frequently partner to take on Alibaba, most recently backing several of the same online and offline retail companies, including Vipshop and Better Life. Walmart and JD.com also signed a strategic partnership in 2016 to combine their resources in China.

JD.com currently operates a sponsored AI research lab called the SAIL JD AI Research Institute with the Stanford Artificial Intelligence Laboratory. The company already uses blockchain technology in its supply chain to track products and AI in software it developed to control its logistics drones and automated package sorting centers.

Here are more details about AI Catapult’s inaugural batch:

CanYa—Based in Australia, CanYa is a peer-to-peer marketplace that lets users pay for digital or home services with cryptocurrency. During the program, CanYa will be marketed to JD.com’s customers.

Bitcoin may be reaching for new heights, but don’t expect AWS to launch a service that’s based on the underlying blockchain technology anytime soon. During a press conference at AWS’ annual re:Invent conference in Last Vegas, AWS CEO Andy Jassy took a question on his team’s plans for a blockchain service.

Jassy seemed anything but enthused about the prospect. In his view, there aren’t a lot of use cases of the blockchain “beyond the distributed ledger.” He also stressed that AWS doesn’t “build technology because we think it is cool.”

In his view, there are plenty of other ways to solve the problems that blockchain technology aims to solve, too, and that many of the distributed ledgers available right now remain very limited in their capabilities.

Still, he allowed for some room to work on a blockchain product in the future: “We are very intrigued by what customers are ultimately going to do there,” Jassy said.

AWS competitors like Microsoft and IBM seem to feel more bullish about blockchain services and distributed ledgers. Over the course of the last few months, we’ve seen a number of them launch both blockchain services and pilot projects with a number of their customers. For the time being, though, it doesn’t look like Amazon plans to join this group.
